Not all tadpoles will survive let alone survive to frogdom. Your koi will eat off a few (not all) however most of the frogs will leave the pond. Unless you have an acre or so there will not be enough food for all the frogs and they will move away in search of a larger body of water, more food and mating.
A management information base (MIB) is a database used for managing the entities in a communications network.hile intended to refer to the complete collection of management information available on an entity, it is often used to refer to a particular subset, more correctly referred to as MIB-module.
So the MIB is used to define what variables can be read from the device. There can be a MIB for a Cisco switch, a MIB for a HP switch and so on. With OID you can read a specific variable from the device, one example being to look at counters for an interface. SNMP is the standard and MIBs are part of that. I recommend that you read through the Wikipedia article on SNMP. It's a good start.
